Hello Gulfstream,
> Thanks for your reply! My next question is How to connect the xrdp server > using remmina client? I don't find where to set the glyph cache. in the previous mentioned upstream link to the remmina bug tracker in comment [1] is written that they added such flags, but I guess the version in buster does not yet contain it. My best hint would be to check for it in the version in buster-backports, as a workaround. > ... And When will the bug be resolve? This has to be answered by the xrdp maintainers. Kind regards, Bernhard [1] https://gitlab.com/Remmina/Remmina/issues/1770#note_120907885
